What is the issue with PMA and PMD in relation to the DWDM network? From an IEEE perspective – they are two well defined terms, and i have not heard any confusion about this in relation to the discussion underway.

As discussed on this week's ad hoc call, there is a need for us to spendsome time on terminology related to the proposed PHY over DWDM network, .Establishing a common reference point for various terms will enableeffective discussions in our group and the industry.

To that end - I am kicking off this thread to try and identify the termsthat we feel need defined related to this topic. This will also serve asinput into a potential liaison to the ITU-T, where we will request theirrespective definitions of these terms.
